Press Release Details

LAWRENCEVILLE, N.J., May 16, 2016 /PRNewswire/ -- Celsion Corporation (NASDAQ: CLSN), an oncology drug development company, today announced financial results for the quarter ended March 31, 2016 and provided an update on its development programs for ThermoDox®, its proprietary heat-activated liposomal encapsulation of doxorubicin and GEN-1, an IL-12 DNA-based immunotherapy.

"We are extremely pleased with our product portfolio, our progress and the investment we have made in gene-based therapeutics," said Michael H. Tardugno, Celsion's chairman, president and CEO. "Over this past quarter alone, we have reported meaningful developments with both ThermoDox® and our immunotherapeutic, GEN-1.  Positive clinical, preclinical and translational data for GEN-1 in both first line and second line ovarian cancer has provided important insights on its potential clinical utility and safety, and reinforced our confidence in the potential of this important investigational product.  We are looking forward to continued meaningful data from our Phase I neoadjuvant trial, the OVATION Study, throughout the year and its support for launching the Phase I/II clinical study later this year to evaluate the combination of GEN-1 with Avastin® and Doxil® in platinum-resistant ovarian cancer patients."

Mr. Tardugno continued, "We have made great strides to advance our global Phase III OPTIMA Study evaluating ThermoDox® in primary liver cancer with clinical sites currently enrolling patients in 13 countries world-wide.  With enrollment now open in China and approximately 50% of the 850,000 new cases of primary liver cancer diagnosed each year originating there, China represents a significant market opportunity and key element of our global development and commercialization strategy for ThermoDox®. We expect to add up to 20 additional clinical sites and enroll more than 200 patients in the China territory, the minimum number required by the China FDA to file a New Drug Application (NDA), assuming positive clinical results."

Recent Developments

ThermoDox®

Enrolled the first patient in the OPTIMA Study in China. On April 26, 2016, the Company announced that the first patient in China has been enrolled in its ongoing global Phase III OPTIMA Study. With China FDA's approval of Celsion's Phase III Study in first line primary liver cancer, the trial is now enrolling patients in 13 countries globally.  With the addition of these Chinese clinical sites, the Company expects an increase in the rate of recruitment sufficient to complete enrollment in the OPTIMA Study by the end of 2017 or early 2018.  Results from the OPTIMA Study, if successful, will provide the basis for a global registration filing and marketing approval.

GEN-1 Immunotherapy

Announced positive data from the first cohort of patients in the Phase 1b OVATION Study.  In May 2016, the Company announced data from the first cohort of patients in its Phase Ib dose escalating clinical trial (the OVATION Study) combining GEN-1, the Company's DNA-based immunotherapy, with the standard of care for the treatment of newly-diagnosed patients with advanced ovarian cancer who will undergo neoadjuvant chemotherapy followed by interval debulking surgery.  In the first three patients dosed, GEN-1 plus standard chemotherapy produced positive clinical results, with no dose limiting toxicities and promising efficacy signals leading to successful surgical outcomes.

• Of the three patients treated in the first cohort, two patients demonstrated stable disease (SD) and one patient demonstrated a complete response (CR), as measured by RECIST criteria.

• All patients had successful resections of their tumors, with two patients having an R0 resection, which indicates a microscopically margin-negative resection in which no gross or microscopic tumor remains in the tumor bed, and one patient with Stage IV ovarian cancer having an optimal R1 resection.

• One patient demonstrated a pathological complete response (pCR). pCRs are typically seen in less than 7% of patients receiving neoadjuvant chemotherapy followed by surgical resection, and have been associated with a median overall survival (OS) of 72 months, which is more than three years longer than those who do not experience a pCR.

• All patients experienced a dramatic &#62 96% drop in their CA-125 protein levels as of their most recent study visit. CA-125 is used to monitor certain cancers during and after treatment. CA-125 is present in greater concentrations in ovarian cancer cells than in other cells. A 50% reduction in CA-125 levels is considered meaningful. All patients' CA-125 levels were below the standard cutoff level of 35 U/mL.

Presented preclinical data for GEN-1 IL-12 Immunotherapy in combination with Avastin® and Doxil® at the American Association for Cancer Research (AACR) Annual Meeting 2016.  In April 2016, the Company presented compelling preclinical data demonstrating significant synergistic anti-cancer effects when GEN-1 is combined with Avastin® and Doxil®, a current standard of care (SoC) for platinum resistant ovarian cancer patients at the 2016 AACR Annual Meeting.  The presentation showed that the three drug combination resulted in a statistically significant reduction of tumor burden of greater than 98% compared to control, and a statistically significant 92% reduction in tumor burden compared to Avastin® plus Doxil® alone.  In contrast, Avastin® and GEN-1 produced a 39% and 50% reduction in tumor burden, respectively.  These preclinical data are consistent with the mechanism of action for GEN-1, which exhibits certain anti-angiogenic properties in addition to its well-characterized immunomodulatory activities. The combination of GEN-1 with Avastin® and Doxil® was well-tolerated with no systemic toxicities. These preclinical data will be used by the Company to support a comprehensive IND protocol filing for a Phase I/II clinical trial evaluating the combination in recurrent ovarian cancer later this year.

Reported translational data from its Phase Ib Study of GEN-1 Immunotherapy in recurrent ovarian cancer.  In January 2016, the Company announced new translational data from its Phase Ib study of GEN-1 in patients with platinum-resistant ovarian cancer. The new data indicated that intraperitoneally-administered GEN-1 produces an immunologically distinct IL-12 protein that is localized at the tumor site and lasts for up to one week after a single treatment.  In addition, concomitant increases in IFN-γ and TNF-α indicate that the IL-12 produced following treatment with GEN-1 treatment is immunologically active.  Celsion intends to collect additional translational data, including cellular responses in primary tumor tissue and peritoneal ascites, in its ongoing OVATION Study, a Phase I dose escalation study in newly diagnosed ovarian cancer patients in the neoadjuvant setting.

Financial Results

For the quarter ended March 31, 2016, Celsion reported a net loss of $5.7 million, or $0.24 per share, compared to a net loss of $7.0 million, or $0.35 per share, in the same period of 2015. Operating expenses were $5.3 million for the quarter ended March 31, 2016 compared to $6.5 million in in the same period of 2015.  This decrease was primarily due to lower research and development and general and administrative expenses in the first quarter of 2016 compared to the first quarter of 2015.

Research and development costs were $3.4 million in the first quarter of 2016 compared to $4.5 million in the same period of the prior year.  In the first quarter of 2015, the Company produced clinical supplies to support both its ThermoDox® and GEN-1 clinical programs.  General and administrative expenses were $1.9 million in the first quarter of 2016 compared to $2.0 million in the same period of the prior year. 

Net cash used in operations was $4.7 million the first quarter of 2016 compared to $5.9 million in the same period of the prior year.  The Company ended the first quarter of 2016 with $14.3 million of total cash and cash equivalents.
